In first product 1.67 has 3 digits and 2.191 has 4 digits, therefore answer should be written up to 3 digits (minimum number of digits used)
In second product 4.76 has 3 digits and 3.12 has 3 digits too, therefore answer should be written up to 3 digits (minimum number of digits used)
In last product 1.6 has 2 digits only hence 3.9 (rounded off) is the answer.
Every circle intersects other circle in maximum 2 points or minimum 0 point.
Total number of combinations of circle are 10 hence maximum points are 20.
Minimum intersecting points are 0.
Total no. of combinations are 4*3*2*1=24
There are 6 ways for making a pair of B-a, similarly 6 ways are possible for the pair A-c in these ways 2 ways are common hence total no. of rejected ways
=6+6-2=10
Similarly 6-6 ways are possible for the combination of C-b and C-d, in these ways 3-3 ways are affiliated with pair A-c and B-a hence only 3-3 ways are acceptable
A representation for the pair C-b is
C-b A-a B-c D-d (selected)
C-b A-a B-d D-c (selected
C-b A-c B-a D-d (rejected)
C-b A-c B-d D-a (rejected)
C-b A-d B-a D-c (rejected)
C-b A-d B-c D-a (selected)
Some statements and their codes are given below
LIFE IS A DEEP MYSTERY 4
GOD IS THE CREATURE 3
UNIVERSE IS UNLIMITED 4
in this coded language EVERY END IS A START is written as
The alphabet E comes 4 times in statement LIFE IS A DEEP MYSTERY.
No other alphabet comes
more than E in the statement hence code is 4.In statement GOD IS THE CREATURE the alphabet
E comes 3 times and no other alphabet comes more than E in the statement hence code is 3.In statement UNIVERSE IS UNLIMITED the alphabet I comes
4 times and no other alphabet comes more than I in the statement hence code is 4.
Similarly in the statement EVERY END IS A START the alphabet E comes 3 times and no other
alphabet comes more than E in the statement hence code is 3.
A B C D E F G H I J K L M N O P Q R S T U V W X Y Z
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26
For VALUE
Difference of places of V & A / A & L / L & U / U & E / E & V are respectively
21 11 9 16 17
Alphabets in these positions are U / K / I / P / Q
Similarly for TRUE
For HEARTH :
Difference of places of H & E / E & A / A & R / R & T / T & H / H & H are respectively
3 4 17 2 12 0
Alphabets in these positions are C / D / Q / B / L / …..
No alphabet is used for position 0
Now for TABLET
Difference of places of T & A / A & B / B & L / L & E / E & T / T & T are respectively
19 1 10 7 15 0
Alphabets in these positions are S / A / J / G / O /…..
Here 168 is equal to 168 minute = 2 hour /48 min = 1/24
And 207 is equal to 207 minute = 3 hour/27 min = 1/9
Similarly 24 is equal to 24 minute = 0 hour/24 min = 0
Therefore 278 is equal to 278 minute = 4 hour/38 min = 2/19
Names of 10 friends are
RAHUL, MOHAN, AKBER, SUNIL, LALIT, AASHU, GOKUL, IMRAN, KANIK & SUMIT
These names are arranged in increasing order according to a coded method.
If out of these 10 names
RAHUL is coded as 7
GOKUL is coded as 8 and
IMRAN is coded as 6
then in this coded language MOHAN is
A B C D E F G H I J K L M N O P Q R S T U V W X Y Z
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26
For RAHUL sum of positions of alphabets = 18+1+8+21+12=60 7
For MOHAN sum of positions of alphabets = 13+15+8+1+14=51 4
For AKBER sum of positions of alphabets = 1+11+2+5+18=37 1
For SUNIL sum of positions of alphabets = 19+21+14+9+12=75 9
For LALIT sum of positions of alphabets = 12+1+12+9+20=54 5
For AASHU sum of positions of alphabets = 1+1+19+8+21 = 50 3
For GOKUL sum of positions of alphabets = 7+15+11+21+12= 66 8
For IMRAN sum of positions of alphabets = 9+13+18+1+14= 55 6
For KANIK sum of positions of alphabets = 11+1+14+9+11= 46 2
For SUMIT sum of positions of alphabets = 19+21+13+9+20 = 82 10
On arranging them in increasing order, MOHAN should be coded as 4.
